Reading XML Elements In .NET?

Mar 11, 2010

I have been learning VB.NET and am currently having troubles retrieving data from an XML file. I'm trying to keep the code as simple as possible as I only need to select single items from an XML file, not rows of data.

The XML file contains:

<CurrentPeakUsage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://au.com.amnet.memberutils/">
<Period>

[code]....

While the msgbox will contain the entire XML document, so it is loading correctly, I can't pull the single element value.

Html - Dynamically Created Elements From Codebehind Need To Be Inserted Between Specific Elements

Sep 17, 2010

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

Accessing Elements Of Readfield?

May 9, 2012

I've managed to get my CSV file opened and the individual elements of each line read into an array. I've also managed to count and list the number of elements in the first row (i.e. the column headers).


[code]...

listOfNewFileRecords.Add(currentRow)' ADD EACH RECORD TO THE LIST AS THE FILE IS BEING READ Now the next stage is to access various cells within the whole opened file, so that I can condition/modify the text.So does 'ListOfNewFileRecords' have a way/method of accessing a particular element, in each record of the 'List'? I've tried using the intellisense, but can't make enough sense out of it to get anything to work.

Adding Elements In Array?

Feb 25, 2009

I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-

[Code]...

Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.

C# - Scrambling Text Elements In XML

Oct 8, 2009

How is it possible to take an XML document and in .Net scramble all text elements to make them un-readable to a human?

[Code]....

We only need scrambling not encryption, i.e. not human readable at a glance. It doesnt matter if the user could de-code it with 30 seconds effort. We dont know the schema of the XML, so all text elements must be located in code. We need to de-scramble the XML later how one would do that too. It needs to be simple, e.g. no pre-sharing keys, certificates, etc. Only the text elements should be scrambled - not the nodes, attributes, etc.

Changing UI Elements From Another Thread In .NET?

Dec 17, 2009

I don't get it. If I want to change the text on a button from a thread other than the UI thread in Visual Basic .NET, I need to use a delegate, and do something along the lines of

Private Delegate Sub SetTextDelegate(ByVal TheText As String)
Private Sub delSetText(ByVal TheText As String)
Button1.Text = TheText
End Sub

[code]....

Of course I can make more generic functions that aren't so hard-wired. But still, it seems like a lot of typing. Am I doing this in a roundabout way? How is this not included in the control properties?
